Learn about Self Test
Google Nest Protect tests itself to make sure that its batteries, sensors, speaker, horn, and Wi-Fi connection are working. You’ll see the results in the Nest app and during Nightly Promise when you turn off the lights for the night. You don’t need to worry if the batteries are low, if the speaker is working or if Nest Protect has any other problems. You’ll know.
What Self Test checks
There are some differences between 1st and 2nd generation Nest Protects; only 2nd gen Protects can check their speaker and horn. Nest Protect's Self Test automatically tests the following things:
- Sensors: smoke, carbon monoxide
- Audio: speaker and horn (2nd gen Nest Protect only) Learn more
- Power: battery charge (including backup batteries for wired Nest Protect) and 120V or 230V (depending on your region) line power connection for wired Nest Protect
- Wi-Fi connection: so you can receive alerts and notifications on your phone.
Note: Wi-Fi connectivity can vary over the course of the day because of wireless interference, service interruptions and other factors. To avoid sending you repetitive notifications when your Internet connection is spotty, Nest Protect will show you it's offline if it hasn't been able to connect to the Internet in the last 48 hours. Nightly Promise will glow yellow, and you'll see the information in the Nest app.
The 2nd generation Nest Protect also runs a Sound Check once a month, to test its speaker and horn - without you having to be at home to run the test.
